This invention relates to devices for accumulating, indicating and recording retail sales transactions.

The main object of the present invention is to provide an improved and simplified sales recording machine. A feature of the invention is the construction of the machine in separate units which may be easily removed and assembled.

An object of the invention is to provide an autograph recording device in which written information is impressed in triplicate on a record strip and a perforated card for the proprietor of the machine in addition to the receipt given to the customer.

Another object of the invention is to provide a retail sales recorder or cash register for producing a perforated record which carries written information in addition to the perforations therein representing the date, transaction, department, clerk, and amount of a sale.

'Another object of the invention is to provide a serial numbering device which cooperates with the series of records at an autograph opening without interfering with the free motion of the hand when writing at the opening. The serial number is impressed in triplicate on the receipt, record strip, and perforated card to identify the recorded information common to each transaction.

Another object of the invention is to provide an improved form of interlock between the keyboard and driving means to prevent operation of the machine unless a transaction key is depressed. A machine operating key must also be depressed before the machine operation is initiated. The

machine is locked if a key is only partly depressed.

The interlock works in a reverse manner to lock the keys while the machine operates. Other connections to the interlocks are adapted to lock the machine when the record strip storage roll is full and when the card stock is exhausted.

Another object of the invention is to provide an indicating mechanism with indicator drums which move towards a home position simultaneous with the movement of the indicator operating means towards anew setting. The indicating devices are provided with individual adjustments for setting the indicator drums in each denominational order.

A fin'ther object of this invention is to provide an improved form of adding and subtracting accumulator. The accumulator includes a transfer mechanism which serves to turn the accumulator wheels in either of two directions to enter and deduct additive and subtractive carry units. Each accumulator wheel is mounted on a separate removable frame.

Another object of the invention is to provide an improved form of card shearing, punching, and ejecting device. Each punch and associated die are mounted on a common settable frame with connections to the keyboard for adjustment.

Another object of the invention is to provide a keyboard which is flexible inasmuch as the keys thereon are adapted to be rearranged for various kinds of sales work. In the present disclosure one group of transaction keys controls subtraction operation, while another group of transaction keys in the same bank controls adding operation, and a third set of keys in the bank controls nonadding. p

The arrangement of the keys in the transaction bank is optional, because the accumulator contr 1 exercised by this bank is so devised that a key in any position in the bank may select nonadding, adding or subtraction operation of the accumulator.

Another feature of the invention is an improved form of paper feeding device. The record materials are fed by a pair of rollers one of which is movable out of engagement with the other. Leaf springs connected to arms carrying the movable roller, not only serve to press the roller in feeding position, but also act as links for raising the roller frame.

The construction of the illustrative machine is shown in a set of drawings which accompany and form part of the specification.

In the drawings:
